We have an application were a external PLC need to control the engine speed. The PLC has 0,5 - 4,5V output zo if we can translate this to requested engine speed we have the solution. I have seen it is available in the MPC-20 so has some body a PV380 config with this in it??

The software engineer said:

The feature doesn’t exist, but if they have the full tool I think they could make it work.

Create a curve for percentage of throttle based on an analog input from 0.5V to 4.5V:
Create an IO definition off of that. The IO.0-5 Throttle Input variable should have a percentage value / 100 (so 0.50 is 50%):
Add it in the connection tab:
The math would look like:

(Idle_Speed + ((Run_Speed – Idle_speed) * IO.0-5 Throttle Input)) * 8

The multiply by 8 is because the TSC1 changes 1/8 of an RPM.

Set the output of this to the variable SPN 898 Engine Requested Speed and it should work. There are some calculations on the TSC1 value that will probably have to be removed so the user keys won’t change the value out from under the calculations made by the analog input.
